AbstractTo determine whether trichobitacin, a novel ribosome-inactivating protein purified from the root tubers of trichosanthes kirlowii, possesses the anti-HIV activity. Methods: the inhibition of syncytial cell formaion induced by human immunodeficiency virus type 1 (HIV-1) was determined under microscope, reduction of HIV-1P24 antigen expression level was measured by ELISA, and decrease in numbers of HIV-1 antigen positive cells in acutely and chronically infected cultures were detected by indirect immunofluorescence assay. Results: Trichobitacin was found to greatly suppres syncytial cell formation induced by HIV-1 and to markedly reduce both expression HIV-1 p24 antigen and the number of HIV-1antigen positive cells in acutely but not chronically HIV-1 infected culture. The median inhibitory concentration (IC^50) in inhibition of syncytial cell formation and HIV antigen positive cells were 5 μg.L-1(95 % confidence limits: 1,3-20 μg.L-1) and 0.09 mg.L-~1(95% confidence limits: 0.011-0.755 mg.L~1), respectively. Conclusion: Trichobitacin is a novel ribosome-inactivating protein with anti-HIV-1activity.
